LANSING ONDERDONK, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE UNION SPECIAL SEIVING MACHINE COMPANY, OF CHICAGO, ILLINOIS.

FlLLED-BAG-SEWING MACHINE.

SPEQIFICATION forming part of Letters Patent No. 583,388, dated May 25, 1897. Application filed June 8,1896. Serial No. 594,759. (No model.)

To aZIwhom-zizf may concern:

Be it known that I, LANSING ONDER DONK, a citizen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented certain new and useful Improvements in Filled-Bag-Sewing Machines, of which the following is a description, reference beingliad to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in sewing-machines, and particularly to mechanism for sewing up the mouths of filled sacks or bags, the object being to provide anonstruction in which the loaded bag or sackmay be delivered at the proper speed to the stitchforming mechanism of a sewing-machine,

and to this end the invention consists in the matters hereinafter described, and referred to in the appended claims.

The invention is illustrated in the accompanying drawings, in which Figure 1 is an end view of the mechanism embodying my invention. Fig. 2 is a front View. Fig. 3 is a side view illustrating a slightly-different manner of delivering the bag to the sewing mechanism. Fig. 4.- is a front view of the device shown in Fig. 3. Figs. 5 and 6 are detail views of a part of the sewing-machine-supporting mechanism, and Fig. 7 is a detail view of the bag-holder.

In the drawings, and referring first to Figs. 1 and 2, A represents a suitable supportingframework composed of the timbers a, a and B, the latter extending forwardly at an incline and being securely bolted to the floor and to the timbers Ct a in any suitablemanner. This inclined timber or support 13 is provided at a point near its upper end with a rack 19, having a series of teeth with which are adapted to engage the teeth on a wheel 0, supported on the same shaft with a handwheel at, which shaft is j ournaled in bearings on the metallic piece 0. (Shown in Fig. 5.) This metal piece 0 is open at its ends, but has projecting sides which embrace the beam B, and, as above intimated, has bearingpoints 6 for the shaft, on which the handwheel d is secured. It will be seen by reference to Fig. 1 that in the turning of the handwheel the teeth of the wheel 0 will engage the teeth on the rack 12 and move the part 0 up or down, as desired. To clamp the part C in any desired position upon the beam B, the cam-lever f is provided. At one end the part 0 is provided with a lug g, extending at an angle thereto, said lug being provided with an opening and being adapted to fit between two lugs h, having similar openings on the plate D, this plate D being pivoted to the part 0 by suitable pin passing through the openings in the lugs g h.

A sewing-machine, herein shown as of the type known as the Union Special Cylinder Machine, is attached by suitable screws to the plate D, and in order to adjust the plate D toward and from the part 0 screws 1' k are provided, the screw 2 passing through the plate D and bearing against the face of the part 0, while the screw it passes through the plate D and into a lug Z on the part 0. By this arrangement the angle of inclination of the sewing-m achine with the beam B is varied at will, and it will be seen that the work-plate of the sewing-machine is arranged at an incline or approximately vertical position,while the needle reciprocates approximately horizontally. Hence no arrangement has to be provided for especially bending over the mouth of the sack or bag to be sewed in order to bring it under the action of the stitch-forming mechanism, but all that is required is to feed the sack in its natural vertical position to the stitch-forming mechanism. I accomplish this in the arrangement shown in Figs. 1 and 2 by providing an endless carrier E, arranged on an incline and traveling over pulleys F F, the speed being controlled by a suitable weight-brake G. By placing the filled sack or bag upon the upper portion of this inclined carrier it is fed at desired speed automatically to the stitch-forming mechanism, which sews up the mouth of said sack. Power is applied to the shaft of the sewing-machine from a suitable supply through pulley m and a belt a, which runs over a second pulley 0, supported on a pivoted bracket 19, attached to the upper end of the beam B and adjusted by means of the thumb-screw q, and from said pulley 0 the belt passes to the belt-wheel r of the sewing-machine.

In order to hold the mouth of the bag or sack together while the sewing is being performed, I have provided a special form ofs' fi holder (illustrated in Fig. 7) which comprises a plate I-I, attached to the beam B and having at its upper end lugs I, through openings in which lugs pass rods K, normally outwardly spring-pressed by the spring L, coiled around the rod'M, which engages the rods K, these rods K at their outer ends being provided with devices for engaging the inside of the bag or sack.

In Figs. 3 and at I have showna modification of the arrangementfor delivering the bag or sack to the sewing mechanism, it comprising. an inclined turn-table provided with a Vertical post N, journaled at its lower end in a suitable standard 0 and at its upperend in a lug or projection P, supported on the beam Band bearing on its under side a j?" cent its. external periphery upon a wheel or roller Q, whichis of diameter suificient, to causethe turn-table to keepan inclined po, sition. It; will beseen that when the bag is placed'upon thisturn-table-it will be deliveredto the sewing mechanism in the same manner asdescribed in connection with. the endless ing up themouths of filled bags or sacks comprisingasupporting-beam, a plate adjustable thereupon, asewing-machine pivoted to said plate and means for adjusting; said plate vertically and for varyingthe angle of inclination at which the sewing-machine is held, andmeans for feeding the bag or sack to the stitch-forming mechanism; substantially as described.

3. The herein-described mechanism for sew position, a sewing-machine adjustably attached to said plate, and means for feeding the bag to be sewed to the stitch-forming mechanism of said sewing-machine; sub- ;stantially as described.

4. In the herein-described mechanism the supporting-beam, the rack thereon, the part O, ashaft supported on said part 0, and: having a toothed Wheel engaging the rack-teeth, a hand-wheel for adjusting said part O 1011- gitudinally ofthe beam, a clamp for holding said part in adjusted position, and a sewing,- machine supported, upon said part C and adjustable to and from the same; substantially i as described.

5. In the herein-described mechanism, the part 0, the, supporting-beam to which the same is attached, the plate D pivoted to the partO, the screw 70 passing through the plate D and engaging the part. 0, and asewingmachine rigidly secured to theplate D; sub.- stant-ially as described.

6. The hereinrdescribed mechanism for sewing up the mouths of bags or sacks compris- LANSING ON DERDONK.
